Well, those who see savings as money kept and should be touched are probably confusing savings with investment, this are two different things, money can be invested as well as saved, money invested i think should be touched until the goal to which the money was invested for, is reached, but on the other hand, money that is saved is saved to be spent later in the near future, those who feel bad when they spend money they saved probably don't understand the meaning of saving, like I said earlier
There is nothing like money investment in that way, you can invest in coins like bitcoin, you can invest in gold, properties like real estate, you can not invest in money unless you are making profit from it. The money that you invest on today that continue to decrease in value all the time, is that one investment? To people it is not investment, you just save money. If you want to invest in money, it will be in a way that you will save certain amount in fixed amount for a period of time to be yielding profit, that is not even investment if the value decrease more than the money gained from the investment.
